This invention relates to avBerlnudaf grass plow, and haslfor one of-its objectsto pro? vide a plow of'this character which shall ernbody a fiat blade havingrearwardly diverging inner 'cutting edges and outwardly and rearwardly curvedV outer cutting edges andV `knives extending upwardly Vtherefrom laterally beyond said lastfcutting edges, the' cutting edges and knives adapting'the blade to readily penetrate the soil and ther'o'otsof the The invention has for a' further vobject tov i* provide arplow of the characterstatedwhich fsliall embody rods pivoted to 'and eztending rearwardly from the 1 blade Vand overVV which,

. the sod passes as'it reachesthe blade-,a ground engaging tappetwheehanda rollercarried by the 'rods and engaging the tappet-wlieel'to A207p'er`mit the rods to be rocked or Yvib'ratedbyY the rods removing'tlie" soil, from' the sod the tappet-wheel, the rocking or v'vibrating of assinof over the bars."v

With the foregoing'and 'other' objects in view, the nature of whichjwill appear as the description proceeds, the invention consists in the construction, combination and 'arf rangement of'parts hereinafter f fully described and claimed,l andv illustratedy inthe accolnpanying'` drawings,wherein :e i

upperfside.V shoe l7 is secured torandextends forwardly'and rearwardly beyond the V`fooi', v6, and the ,front portion ofthe shoe Vhasy a downwardly and forwardly inclined 'upper side located inv alinement withl the corf` f responding side Vofthe foot. The shoe' Lis provided iny its uppersidelw'ith a recess 8 for therec'eption ofthefoot 6', and'is secured to' the, footaby bolts 9. A'plate 10 restsupon 'the inclined'upper sides of the foot 6 andshoe and -is secured to these parts vby bolts 11.

`'lfhe'platelO extends forwardly and laterallyV Mv,beyondthe foot' and shoe 7, and constitutes a reinforcing element for' a flat" blade' 1f?.Y vwhich` rests upon the plate and is secured pla-ce by the bolts; 1-1 and rivets 1?` in L Thebla'de 12 extends forwardly and'A at- -erallyr-,beyondvthe plate'A 10, and equal poru. tions thereof are locatedatopposite sidesV of :the longitudinal center ofrthe pl0w.'-The' bladeV 12is' provided 'at its frontedge andcenrectio'n' of its front end to provide rearwardly 1 diverging cutting edges 15. The front edges of theblade12 curveoutwardly and rearwardly fromV the' rear end ofthe extension 14 to provide convex euttinge'dges 16. The

blade llfispro'vided--at its side edges i upwardly extending knives 17 which have upftrally between its side-edges--witha forwardly Y V `directed"extension vlsiqwhichV tapers in the diwardlyan'd rearwardly curved cutting edges 18. lIThe'blade l2' and its extension- 14 areV eoplanar, and are supported ina downwardly and'forwardly inclined position. Due there- `to`,and in view of the rearwardly dive'rging inner 'cutting edges 15, the convex outer cut- -tingedgesland the knives 17, the blade will yreadily out through the soil and roots of Bern'nida grass. f l u y v Bearings 19v are secured to the underside of the blade'l near the' rear edge of the latter.V

front sides of the shafts 20, and the shoulders formed by reducing the ends of the bars and contacting with the rear sides of the shafts, serve to secure the bars to the shafts. The bars 21 of each shaft are relatively spaced, and are maintained in spaced relation by collars 28. l A rod 24 screw-threaded throughout its entire length passes through each group of the bars 21 and the, spacing collars 23, and is held in place by nuts 25.

The innermost of the respective grouljs `of bars 21 are connected by a shaft 26, and rotatably mounted upon the shaft between-such f bars is a. roller 27. The ends of the roller 27 are protected by housings 28 carried by the shait,26; i 1Braees=-29` extend from the .upper side-of the rear endet thesshoe 7 tothe underside ofthe blade 12, and# are -secured to these parts, 'as shown at `30 `and; .31, .respectively.`

The braces 29 are `located below the bars .21 serve to limit thedowfnward swingingor `rechi-ngel-movementof thepbars. i A 2 A-notched sector 32 is'lo'cated rearwardly of the -standard .2 and between therespective .groups of bars 211, `and 'is secured, as Aat 33, to the standard; Anlangul'ar lever-Seis piv- -oted atthe `junctnres 'of its arms 35 'and I36 to the sector 32, thearm--35"-erttending down- "wardly Iand rearward-ly yfr'omthe j p'ivot A37, Aand thaarm 36 jentending upwardly :and rearwardly romthe pivot.

'itw-ill :be understoodthat the colteri Savill cut 'i the sod4 in l advance: o'ffthe' blade extension ld,

and that the blade 12 will, due to its inclination, lift the sod which is cut at each side of the blade by the knives 17. rlhe sod will pass from the blade 12 onto the bars 21 which will be rocked or vibrated by the tappet-wheel 38, resulting in the loosening of the soil from the sod.

' While 1 have 1described 'the principle of the invention, together with the structure which I now consider the preferred embodiment thereof, ilt ie to-bennderstood that the structure shown is merely illustrative and that such changes may be made, when desired, as fall within the scope of the invention as claimed.
